Abstract

559,020. Polystyrene moulding compositions. BAKELITE, Ltd. Julv 28, 1942, No. 10556. Convention date, Aug. 1, 1941. [Class 2 (iii)] A resinous moulding composition comprises polystyrene and a mould lubricant consisting of up to 1 per cent. by weight of the composition of a defined polyalkylene oxide having an average molecular weight greater than 400. Preferred proportions are 0.1-0.7 per cent. by weight and the preferred lubricant is polyethylene oxide. The polyalkylene oxides are long chain polyalkylene glycols formed from an alkylene oxide and an alkylene glycol or an alkylene glycol mono-ether, and include mixtures of polyalkylene oxides. The composition may be made by simple mixture or by mixing the lubricant with monostyrene and then polymerizing. In examples mixtures are made of polystyrene, polyethylene oxide and (1) black dye, (2) titanium dioxide and red dye. In examples (3) and (4) polyethylene oxide is mixed with monostvrene and the mixture polymerized. Specifications 349,638 and 352,042 are referred to.
